in the construction of magnetie moo it oscillatory type and has for itsobject to a. simplified construction which will 5 and dependable in itsoperation and which will moreover be operable with the minimum require=ment of electrical energy thereby to adapt it for e, or e economioaloperation over extended periods by 32123 lent battery current. 10Important features of the present invention reveteeiy which contributeto the economical operation of from my improved device consists in theemployment, sitely as the actuator or impeller member, of e, pivotellythe supported arm carrying at its lower end a magnet l5 coll operativeas a. pendulum Weight and eoo ier= ends sting with a, fixed. armaturerod served to @Qi'i or iingze form to the oath of movement of the coiloolnbined with a, make and break control s toll improved type adaptedperioilieslly and lo? a; 99 short interv only to energize the eel! ic pc duci'ng impelllng e 3; actuator suflieient tor maintaining continuedoscillation thereof. The improved control is of a type employing arotazy eontect preferably of ratchet formation rigid v ported andarranged to co-act with e, eon tact member carried by the oscilletirigsell importing a, progressive advance movement to the rotary member ateach stroke the eetu= atom the arrangement providing fol closing thecircuit once for each given number of stro" of the pendulum actuator asdeterm ned the switch formation. There is thus provided a pluraloscillation with relation to the newer 121 35 pulses resulting in a,prime mover petitieilloiiy well adapted for operating advertisingdisplays of light load with the minimum current oon= sumption.
